So as you can see, it has pretty much everything there that may need adjusting; some you will probably never use. I found the factory defaults to be just fine,
except for a brightness/contrast adjustment for my own personal preference. I found the menu easy to use, and the manual explains
the OSD very well, so you shouldn't have any issues here whatsoever.

DisplayMate Tests
Using the handy utility, DisplayMate, I went through all of its tests and was able to have a good close look at the display quality of the monitor.
I have broken it down below into the various sections tested. For all of the tests, I ran them at various resolutions and color depths,
and then summarized my findings.

Geometry & Distortion
This test displays various line patterns and geometric shapes, which gives you an accurate representation of the monitor's ability
to properly display geometric shapes. The only problem I had seen during this test was that the top left and right ends of the monitor were a little
off, but by only a very slight amount.

Sharpness & Resolution
During these tests, the monitor was put through various patterns and lines. The most noticeable thing you will usually see here
is Moiré. Moiré occurs when there is interference between the phosphor layout and the video signal. The iiYama has
an adjustment to compensate for this, and it did a fairly good job of it. After adjusting it, you could still see a small amount of the effect,
but nothing to be concerned about.

Screen Pixel Resolution
This test is similar to the Geometry test. It displays various line patterns and shapes. Here again, you are looking at the Moire effect - jagged lines,
rippled effects in the images, and lines that start to mesh together. I really didn't notice anything out of the ordinary here, because I had already adjusted the Moire control
a bit earlier in the Sharpness tests. So, the effect was barely noticeable. There was some minor rippling when the lines were incredibly close together, but
after doing the same test on a Viewsonic G790, the iiYama's clarity was evident. You will rarely, if ever, find a monitor that can go through all these tests
and score perfectly.

Color and Gray-Scale
Now we get into the monitor's ability to display colors. One of the most important things to look for here is misconvergence. Misconvergence
is essentially the misalignment of the red, green, and blue electron beams. The iiYama did fairly well here. There was a tiny bit of it at the very
edges of the screen, where it's usually most predominant. By using the H-Convergence and V-Convergence functions, I was able to eliminate 80% of it.
Where this affects you in day-to-day use of the monitor is in the overall sharpness of images and text. I did not see any evidence of this, aside from in the
tests.
